This defect will go to Linux as even after making the below 2 changes in systemd resource limit, errors are seen:
root@yellowbee:/etc/systemd/logind.conf.d# cat htxlogindcustom.conf
[Login]
UserTasksMax=infinity
root@yellowbee:/etc/systemd/logind.conf.d# cat ../system.conf.d/htxsystemdcustom.conf
[Manager]
DefaultTasksAccounting=yes
DefaultTasksMax=infinity
root@yellowbee:/etc/systemd/logind.conf.d#
logind limit for MaxUserTask as well as systemd limit was made infinite.
Please look defect SW363655 for more details and the suggestion given earlier by Linux team.
errors are still seen. So, would ask Linux team to take a look and see if anything else is causing these
errors.
== Comment: #3 - Kevin W. Rudd <ruddk@us.ibm.com> - 2016-12-19 17:34:27 ==
It appears that the version of logind on this system does not support the value of "infinity", and is reverting to the default of 12288:
# cat /sys/fs/cgroup/pids/user.slice/user-0.slice/pids.max
12288
As a workaround until this can be resolved, specify an exact value. You can try using the current system thread-max value:
# cat /proc/sys/kernel/threads-max
3974272
/etc/systemd/logind.conf.d/htxlogindcustom.conf:
[Login]
UserTasksMax=3974272
== Comment: #4 - Kevin W. Rudd - 2016-12-20 10:25:09 ==
Canonical,
This issue appears to map to the following systemd bug and patch:
https://github.com/systemd/systemd/issues/3833
https://github.com/systemd/systemd/commit/f50582649f8eee73f59aff95fadd9a963ed4ffea
This patch appears to be included in debian/232-7, but is missing in the xenial and yakkety versions. |
[SRU justification]
Before systemd 232, UserTasksMax=infinity is not respected in logind.conf, despite the documentation referring to systemd.resource-control(5) for the definition of this field. This limits the use of Ubuntu 16.04 and later in contexts where a user session should be permitted to allocate large numbers of processes.
[Test case]
1. Set UserTasksMax=infinity in /etc/systemd/logind.conf.
2. Create a new login session.
3. Check the ulimit for user processes with 'ulimit -u'.
4. Verify that the limit has a numeric value.
5. Upgrade to systemd from -proposed.
6. Create a new login session.
7. Check the ulimit for user processes with 'ulimit -u'.
8. Verify that the limit is now set to 'unlimited'.
[Regression potential]
This is an upstream patch which is part of 232 and later without issues and clearly addresses the bug in question. While the upstream commit includes code changes that are not strictly required in order to fix this bug, these are mostly cosmetic and should not carry significant additional risk.
